1500VDC T2 Surge Protective Device for Lightning Protection Applications
Technical Features
The unit features a standard discharge current rating of 20kA, demonstrating consistent performance under repeated surge conditions. Its T2 classification confirms compliance with international standards for surge protective devices, specifically designed to handle indirect lightning effects and switching surges in electrical distribution systems. The 1500VDC voltage rating makes it suitable for various highvoltage DC applications where reliable surge protection is required.
The incorporated thermal protection mechanism automatically disconnects the unit during overload situations or at endoflife failure, ensuring continued system safety. A visual status indicator provides clear operational feedback through colorcoded display, allowing for quick assessment of the device's condition. DIN rail mounting enables straightforward installation in standard electrical enclosures, while screw terminal connections provide secure wiring implementation.
Application Scenarios
This protective device finds primary application in largescale photovoltaic systems, where it protects solar inverters, combiner boxes, and monitoring equipment from lightninginduced surges. Industrial applications include protection for highvoltage motor drives, control systems, and automation equipment in manufacturing environments. The unit is also suitable for electric vehicle charging infrastructure, telecommunications power systems, and backup power installations where highvoltage DC power protection is required.
Additional application areas include railway electrification systems, mining equipment power supplies, and other industrial settings where electrical systems are exposed to potential surge events. The device provides effective protection for both indoor and sheltered outdoor applications when installed in appropriate enclosures.
